4 Claims.

My invention relates to certain novel improvements in a combined handleand lock and has forits principal object the provision of an improvedconstruction of this character which will be highly efiicient ,in useand economical in manufacture.

Without limiting myself to the use or application of my combined handleand lock, invorder to illustrate the advancement which I have made overthe art relating thereto, I make reference hereinafter to the use andapplication of my invention to the door of a locker such as is employedin school buildings, Workshops, ofces and other like places.

With this in mind, one of the salient objects of the invention is toprovide a combined handle and lock, the latter of which will control theoperation of latch lifting mechanism operable by the hand of theoperator upon grasping the handle and exerting a slight up-ward pressureupon the lifting mechanism to lift the latch bolt or plate from itskeeper plate or opening.

A still further object of the invention is to provide a combined handleand lock which is selflocking upon closing of the door with which it isassociated. l

A still further object of the invention is to provide a lock, themechanism of which may be independently operated by either a permutationlock or a master key.

A still further object of the invention is the provision of a combinedlock and handle which When associated with a doorhaving a liftable latchbolt or plate, operates in a plane parallel with the movement of thelatch bolt or plate thereby avoiding undue Wear on the part of thelifting mechanism and/or the latch bolt or plate as Well as permittingthe lifting mechanism t0 be operated by a minimum pressure of the handagainst the lifting mechanism thereby eliminating the possibility of thelatch bolt or plate and its lifting mechanism from being thrown out ofalignment with respect to each other and with respect to the keeperplate.

A still further object of the invention is the provision of liftingmeans for a latch plate or member which is in direct connection with thelatch plate or member thereby assuring efficient and expeditiousoperation of the entire mecha- 50 nism.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of partsto be hereinafter described and claimed.

Theinvention will best be understood by refer- (Cl. M -207) ence to theaccompanying drawings, showing the preferred form of construction and inwhich:

Construction Referring more particularly to Figs. 7 to 9, inclusive,ywherein there is fragmentarily illustrated a cabinet or locker sectionand door thereof, The door is indicated lat I0 and is of a conventionaland well known design. This door is provided with lateral marginalflanges I I. Mounted on and connected to one of the marginal flanges IIindicated at AI I for movement longitudinally and parallel with theinnerrface of this flange is a plate I2.

This connection between the plate I2 and flange I I Y is accomplished inthe usual manner by means of slot and pin connections I3.

At predetermined points upon this plate I2 are provided spaced latchfingers Id adapted for engagement with keeper plates I5 secured to theadjacent side jamb I6 of the cabinet or locker.

Secured to the plate I2 is a laterally extending arm I'l having formedtherein an opening I8 in registration with an elongated slot I9 formedin the door.

The plate I2 and arm I'I are associated with the door in the mannerabove explained so as to gravltate into position to dispose the latchngers I4 into latched engagement with the keeper plates confined. v Y

To complete the handle-there,V are provided extended portions or ears 22and 23 perforated as at 22Yfor the passage of connecting elements 24preferably in the form of nut receiving bolts.

These connecting elements 24 are utilized for Vconnecting the handle tothe door Il) as best 1 shown in Figs. 7 and 8. Y

The rear portion of the casing ZI is open an-d when the lock mechanismis. assembled therein this open rear portion is normally closed by a'plate 25 parallel to which is Slidably arranged a lift 26.

This liftI 25 includes a horizontally extending portion 2iat its lowerend from-which extends a web or iin 28 for reasons hereinafter morefully understood.

Extending laterally from the lift-25 is a pin 29 adapted. for operativeprojection through theV elongated slot I9 formed in the door, the innerend of the pin 29 fitting into the opening I8 of the arm VI of the plateI2.

The lock mechanism is obviously concerned withv the locking of this lift`26 against Voperation and this mechanism will Vnow be described indetail. v Y Y Y Y The casing 2|l in its front wall is provided with anopening 30. Rotatably mounted in this opening 3@ is a knob-3l havinga'beveled body portion-32 which-bears a dial 33 including numericalcharacters and indicating lines 34;

The knob 3I is provided with an Yannular flange 3.5 which operativelyand movably engages the.V

adjacent edge portion 35 of the-opening 39. y.

This knob 3l includes a sleeve `3'I .which nts over the sleeve V38within which is housed the lock mechanism.

This sleeve 38 serves to support'the mechanism,V

operated by the mechanism of the permutation lock which i will nowexplain.

Secured to the closure plate 25, as by rivets 25',V

is a supporting structure 39 from which is supported the'sleeve 38 asshown at 4i).

Mounted upon this sleeve 38 forwardly of the supportingstructure plate39 are the permutation discs 4 l. The discs 4I are of the usual wellknown construction and include the combination changing rings or keys i2together with the means 42 for rotating the permutation discs about theYsleeve 38 so as to permit operation of the lift upon placing thepermutation discs in proper registration pursuant to a predeterminedrotative movement of the dialfSI. t The peripheral edges of the discs4I'arev provided with notched out portions to provide a shoulder 43 intowhich is adapted tobe engagedy a spring urged pawl 44 which isYpivotally mounted on the lift 25 as best shown in Figs. 5, 5A, 6AV andVY6B. The function ofvthis'pawl which is normally urged by a spring 58 ina counterclockwise di- Y rection, Figs. 6 and 6A, will be made moreapparent hereinafter. Y

Pivotally supported by the supporting structure Stils a member 45 whichhas formed therein at one side edge thereof a recessed portion providinga shoulder 4B.

The pivoted member 45 is provided with a laterally extendingrestraining'nger 4l which permits` pivotal movement of the member 45about its pivotal Vconnection 48 to the supporting plate 35 only whenthe notches i9 oi the permutation discs are in registration with respectto each other, as is best illustrated in Fig. 5A; and the member 45 isurged, by a spring 55, Fig. 6 in a direction (clockwise, Fig. 6) toproject its lateral extension 47 into the notches 49 in the discs 4Iwhen the latter are registered with each other.

Formed in the lift 26 is an elongated slot 29 through Vwhich a pin 5E!which is supported by the plate 25 projects', and pivotally supported bythis pin 50 is a latch arm 5I.

This latch arm 5I is normally urged by a spring into position so as todispose the lower end portion 52' thereof into obstructing position withrespect to the web or nn 28. Y

' The latch arm 5I=includes an upper end portion having a pair ofroffsetdivergent extensions or shoulders 52 and 53, shoulder 53 being normallydisposed, b-y action of the spring 66.', in a position 'to engage anextended portion 54 of the pivotal member V45, for reasons which will bebest understood hereinafter.

The offset shoulder 52 of the latch member 5I is separatedV .fromshoulder 53 by aV concave shoulder 55V and is adapted to be engaged bythe nose .portion or rise 576 of a cam 51 whichV is mounted upon a shaftportion or extension 58 of a lock barrel 59, which is rotatably mountedwithin theV sleeve 38- and within which'a plurality of Vtumblers 5Uare'mounted, these tumblers 60 being codied to a service or master keywhich controls the operation of the lock barrel 59 and consequently theoperation of the shaft 58, as best shown in Fig. 3. .A Y

'I'he lift 25 is normally urged into a lowered Operation Y The cam 5l isnormally disposed in the position of Fig. 6A with its nose portion orrise 55 extending upwardly andthe lift 26 and the latch pin 2%l carriedthereby are normally Yprevented frombeingraised Yor lifted, toV effectthe door unlatching operation, by reason of the fact that the lower endportionr52 of the pivoted latch member 5| isnormally disposed directlyabove the transverse web or stop portion 2B oi the'lift 26'as shown inFigs. 6 and 6A. However, as will now be described, the operator may movethe lower end portion 52V' of the latch member 5I out of verticalalignment with the stop portion 25' or^ the lift 25 in either of twoways, that is, either by manipulatingthe combination knob and dial 3land thel permutation discs Y4I into position to register the notches 45in the discs 4I with each other; or, by inserting a proper key 5I intothe lock cylinder or barrel 59 Yso as to operate the cam 55-5`L in amanner which willbe explained presently.

When the combination knob and dial 3i, and the permutation discsV 4I,are manipulated into position to register the notches 49 in thepermutation discs el with-each other, a spring 65 acts upon the member45 to pivot the latter (counter,- clockwise, Fig. 6A) so' as to move theprojecting portion 41 of the member 45 into thev registered `or alignednotches 49 in the permutation discs 4|.

During this movement of the pivotal member 45 (counterclockwise, Fig.6A) the lower end portion 54 thereof engages the upper end portion r53of the latch member and pivots the Vlatter against the action ofitsresetting spring 66, (clockwise, Fig. 6A) so as todispose the lower endportion 52 of the member5|-out of alignment with the transverse weborstop portion 28 of the lift 26, (as in Fig. 6B) thereby permitting thelift 26 to be raised; and ,when the 4lifft 26 is lowered, or reset intoits initial position, the spring 65' resets the latch member 5| intotsnormal postion, as in` Fig.V 6A, so that the lower end portion 52thereofis disposed above and in alignment with the web or stop portion28 of the lift 26.

It will be noted that the latch member 5| may also be pivoted(clockwise, from its position of Fig. 6A to its position of Fig. 6B) soas to dispose the lower end portion 52 thereof out of alignment with thestop portion or web 28 of the lift 26 by inserting a proper key 6| intothe lock barrel 59 and then turning the same and the shaft 58 and cam 51(clockwise, Fig. 6A).

This movement of the lock barrel 59, shaft 53 and cam 51 (clockwise,Fig. 6A) causes the nose portion or rise 56 of the cam 51 to engage theshoulder 52 which isformed in the upper end portion of the latch member5|, thereby pivoting the latch member 5| (clockwise, Fig. 6A) so as todispose the lower end portion 52 thereof out of alignment with the webor stop portion 28 of the lift 26 so that the latter may be lifted.

When the permutation discs 4| are manipulated, by the knob and dial 3|,into position to register the notches 49 therein, the notches 43 in thepermutation discs 4| are also registered. Accordingly, after the lift 26has been raised, to perform the door-unlatching operation, and is fbeing returned by gravity to its lowered position,

the spring 68 acts upon the pivotal member or pawl 44, which is carriedby the lift 26, to urge the lateral extension 61 of the member 44 intoengagement with the peripheral edges of the discs 4|, thereby disposingthe extension 61 of the member 44 in the aligned notches 43 which areformed in the peripheral edges of the permutation discs 4|, as shown inFig. 5A. As the lift 26 continues its downward movement, the lateralextension 51 of the member 44, engaging in the notched portions 43 ofthe permutation discs 44, turns the latter (clockwise, Figs. 5 and 5A),whereupon the cam edges 69 of the discs 4| which define one marginalwall or edge'of the notched portions 49 (Fig. 5A) engage the lateralextension 41 of the member 45 and thereby pivot th'e member 45 (in aclockwise direction, Fig. 6A). This movement of the member 45 moves thelateral extension 41 thereof out of the notches 49 in the permutationdiscs 4|, whereupon the discs 4| are rotated or moved further, in aclockwise direction, Fig. 5A, by the lateral extension 61 of the pawl44. In this manner the notches 49 are moved out of registration with thelateral extension 41 of the member 45, and the combination is destroyed,so that the device can not again be operated by means of the dial 30,until the permutation discs 4| are again manipulated, by a personknowing the proper combination, into '.the pin Y63 carried therebyengages position toV register the` notches 49 with the ylateralextension 411.0fthe latch member 45.

6A) so as to dispose its end portion 54 out of engagement withtheshoulder 53 of the latch 5|. rIt isto be noted, however, that eventhough the device cannot -again be operated, by means ofthedial 30,until the same is operated by a person knowing the proper combination,it may,

nevertheless, be operated by the insertion of a proper key 6|, into thelock barrel 59. Y

Attached to the door lilon the inner side of the latter is a piece offlat spring metal 13 which has an angled upper end portion 10' and thisangled upper end portion 10 of the member 13 is engageable when therdoorl0 is in opened position, with a serrated edge portion 1| which isprovided in the slide bar I2 so as to hold the slide bar |2 in raisedposition when the door lil is open, and likewise holding the main latchmember or lift in effective or latching position, when the door 0 is inopened position. However, when the door ||lis closed an angled endportion 12 of one of the keeper plates l5 (Fig. 9) engages the angledend portion 10 of the latch member 13 and forces the angled end portion1B of the latch member 13 out of latching engagement with the serratededge portion 1| of the slide bar |2, thereby permitting the slide bar l2to drop by gravity and thus moving the lugs I4 on the slide bar I2 intolatching engagement with the keeper plates l5, (Fig. 9).

This downward movement of the slide bar I2 acts upon the pin 29 to movethe latter downwardly in the slot I9 (Fig. 9) which is formed in theface plate of the door IU, thereby lowering the handle 20 and the liftor latch member 26 into their lowered or effective position, whereuponthe spring 66 moves the latch member 5| into position to dispose thelower end portion 52' thereof in a position in alignment with and abovethe upper end of the web or stopy portion 28 ofthe latch member or lift26 so as to prevent unauthorized movement of the latter.

While I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modication, without departing from the spirit of theinvention. I, therefore, do not wish to be limited to the precisedetails of construction set forth, but desire to avail myself of suchvariations and modifications as come within the scope or" the appendedclaims.
